Apple, Amazon | featured news

Apple has sold more than three million iPads since April, but Amazon’s success with the Kindle is cloudier because it doesn’t reveal sales numbers.

Amazon.com Inc. Chief Executive Officer Jeff Bezos cut prices and added features to the Kindle to defend it against a threat from Apple Inc. in the fast- growing market for electronic readers. Amazon introduced two new versions of the device today, including a $139 model that works with Wi-Fi. A second version, with 3G mobile technology as well as Wi-Fi to download books, costs $189. Bloomberg News reported details in May about Amazon’s plans for the Kindle, its bestselling product.
